| Zusammenfassung: | A unit cell is provided with: a bonded member in which a first metal and a second metal are bonded to a current path for charge/discharge current and an interface between the first metal and the second metal is formed; and a sacrificial anti-corrosion layer which is arranged on the bonded member so as to be in contact with the first metal and/or the second metal. The first metal is pure aluminum or an aluminum alloy. The second metal is pure copper or a copper alloy. The sacrificial anti-corrosion layer is formed of a material that has a larger ionization tendency than the first metal. |
